Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 624-76-0, name is 2-Iodoethanol, This compound has unique chemical properties. The synthetic route is as follows., 624-76-0
A solution of 2,3,3-trimethyl-3H-indole (1 ml, 6.3 mmol) and 2-iodoethanol (0.56 ml, 8.8 mmol) in MeCN (4 mL) was refluxed for 1 day. After being cooled to r.t., the reaction mixture was suspended in hexane, and the precipitated solid was sonicated and filtered. A part of the obtained purple solid (53 mg out of 1.37 g) was dissolved in 1N KOH (2 mL) and stirred at r.t. for 30 min. After extraction with ether, the organic layer was evaporated to afford 4 as yellow oil, which was used for the next reaction without further purification. A solution of 5-nitrososalicylaldehyde (38 mg, 0.23 mmol) and the obtained 4 in EtOH (5 mL) was refluxed for 4 hours. The mixture was evaporated and purified by column chromatography (silica gel; eluent, hexane_AcOEt=1:1) to afford purple crystal 5 (56 mg, 66% based on 2,3,3-trimethyl-3H-indole). MS(EI): 352(M+, 15), 337(5), 321(9), 83(100); HRMS(EI): M+352.1411 (calc.352.1423); 1H NMR(CDCl3) delta1.20 (s, 3H), 1.30 (s, 3H), 3.34 (ddd, J=5.1, 5.1, 14.7 Hz, 1H), 3.47 (ddd, J=5.5, 7.3, 14.7 Hz, 1H), 3.69-3.82 (m, 2H), 5.89 (d, J=10.5 Hz, 1H), 6.67 (d, J=7.5 Hz, 1H), 6.77 (d, J=8.5 Hz, 1H), 6.90 (dd, J=7.5, 7.5 Hz, 1H), 6.91 (d, J=10.5 Hz, 1H), 7.10 (dd, J=1.1, 7.5 Hz, 1H), 7.50 (ddd, J=1.1, 7.5, 7.5 Hz, 1H), 8.00 (d, J=2.5, 1H), 8.03 (dd, J=2.5, 8.5 Hz, 1H).
